'A'rnNr I BELT-FASTENER.

SPECIFICATION forming part of Letters Patent No. 322,988, dated July 28, 1885.

Application filed October 29, 1894. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE W. SoUTH- WIOK, of Stamford, in the county of Fairfield and State of Connecticut, have invented a new and Improved Belt-Fastener, of which the following is a full, clear, and exact description.

The invention consists in a belt-fastener comprising a plate provided with two or more teeth having longitudinal ribs on one or more of their faces, which ribs project beyond the upper edge of the teeth, as will behereinafter fully described and, claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an enlarged longitudinal sectional view of my improved belt-fastener, on the line 00 m of Fig. 3, applied to the meetingends of a belt. Fig. 2 is a side view of the belt-fastener and section of one tooth. Fig. 3 is a face View of the same. Fig. 4 is a plan View of the belt-fastener. Figs. 5, 6, and 7 are plan views of beltfasteners, showing different arrangements of the teeth. Fig. 8 is a face View of a modified form of the belt-fastener, only one tooth being shown.

From a plate, A, a series of teeth, B, pro ject, which may be arranged in one or more rows, all parallel with each other; or they may be arranged in groups, as shown in Figs.

5, 6, and 7, the flat sides of the teeth beingsaid part can be bent over the top of'the tooth. The teeth are forced through the end parts of the belt D, the ends of the ribs 0 projecting from the inner surface of the belt,

and are then bent over or clinched toward each other, as shown, the points of the ribs belt D. The ends of the belt can be placed on the plate A, the outer surfaces of the belt facing downward, and by striking with a,

hammer on the inner surface of the belt the ends of the teeth are forced through the belt from the outer to the inner surfaces, and at the same time the ends of the ribs are clinched. The ribs prevent slipping of the teeth, and consequently ripping of the belt ends, and the clinched ends ofthe ribs hold the teeth securely in the belt and prevent pulling them out. The improved tooth possesses the virtues of a clinchable and anon-clinchable tooth, and prevents unnecessary accumulation of metal on the inner surface of the belt.

In place of providing one rib on one side of the tooth, one rib can be provided on each side, both ribs projecting from the upper end of the tooth; but in this case the two ribs on the opposite faces of the tooth are not opposite each other, but are in different vertical planes, so that the projection of each rib can be bent over independently of the other, the said projecting parts being clinched in opposite directions. By clinching the projecting parts of the ribs with a hammer the upper end of the tooth B serves as a fulcrum to bend the rib, and thus the belt need not act as a fulcrum as in other teeth, and thus the grain or fiber is not destroyed by clinching the ribs.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is r 1. A belt-fastener plate provided with teeth having one or more ribs the ends of which project beyond the upper ends of the teeth, substantially as set forth. 7

2. A belt-fastener plate provided with teeth having ribs on their'opposite faces in different planes to each other, the ends of said ribs projecting above the ends of the teeth, substantially as set forth.
